forcing member 10 embedded in a body 11 To all 'whom t 'may concern.' y

Be it knownwthat I, JOHN 'NELSON, a citizen of the United States ofAmerica, residing at Ottawa, in the county of Franklin and State ofKansas, have invented oertain new and useful ImprovementsinReinforced-Concrete Ties, of which the following is a specification. n

The primary object of the invention is the provision of a railway tiethat has long life, is easy and inexpensive to manufacture, and adaptedfor laying upon a road-bed in track formation with great rrapidity.Another object of the invention is to provide an essentially concretetie having a special form of metal reinforcement for" strengthening theconcrete structure and affording a metal seat for the rails which areaccurately gaged by such reinforcement, a rail fastener being alsoincluded as a part of the invention.

A still further object-'iste provide a. metal reinforcing member forconcrete ties and the like, which member being formed of sheet metal iseasily stamped and bent into shape affording strong anchoring means forthe surrounding cement body as well as providingv a metal seat and outerfasteners for t-he rails positioned for use uponthe tie.

1N ith these general objects in view, the invention consists of thenovel combination and arrangement of parts, hereinafter more fullydescribed, illustrated in the accompanying drawing and then claimed.

In the drawing forming a part of this application. and in which like#reference characters designate corresponding l parts throughout-theseveral views,

Figure 1 is a side elevation of the invention with rails shown in.vertical transverse section, operatively secured thereon.

Fig. 2 is a top plan view thereof partially cut away through theconcrete with one rail in position shown in horizontal longitudinalsection.

Fig. 3 is a vertical longitudinal sectional view of an end portion ofthe invention upon an enlarged scale.

Fig. 4- is a vertical transverse sectional View through the tie, takenupon lineI specication of Letters Patent.

of plastic composition of proper length for a railway tie andrectangular in cross section 'being substantially of the same exteriorform and size of the ordinary wooden tie now in use. The sheetmetal-member 10 is 17 of the completed cement tie for seating.

railway rails 18 transversely thereon. Inwardly projecting curved ears'19 upon the outer ends of the extensions 15 are adapted to overlie theouter base flanges 20 of the rails 18 for. spacing the rails. therequired gaged distance apart. accurately positioned 1n track formation.

The opposite edge 1'2 of the blank 10 from A,said edge 12 is providedwith similar slits of slightly less length thanthetie to be I 13 betweenand outwardly of the extensions l15 forming ears 14 for alternatebendingin opposite directions for anchoring `the metal member in theconcrete.

ICopera'tmg fasteners are provided 1nwardly of the rails 18 for use w1ththe ears l 19, the same consisting of inwardly projecting arms 21 uponthe extensions '15 with bolts 22 mounted upright on said arms by meansof longitudinal slots 23 inthe bolts, through which the varms 21 extend.The bolts 22 are in this way mounted parallel to the adjacentinner edgesof the extensions l5 and the inner free ends of said arms are preferablycurved laterally as a't 24, said arms and the enlarged lower slotted endportions or heads 25 of -said bolts being firmly embedded in theconcrete ll'and anchored in position in the formation of the completedtie.

.The bolts 22 project above the top 17 of lthe tie sufficiently spacedfrom the ears 19 to permit the rails 18 to be freely positioned upontheseat 16 with the outer flanges of the rails vbeneath said ears 19. Adetachable clamp or fastener 26 is then positioned upon each bolt 22seated partially upon the top 17 of the concrete and partly 'upon themetal seat 16 of the adjacent extension 15 and a lock nut 27 thenthreaded upon the upper end of each bolt 22 for securing the clamps 26lwith the rail mounted for use transversely of the tie. l l The metalreinforceV 10 is Securely anchored by the ears 14 and 14 within theconcrete 11 vwhich is molded or formed in any usual manner suc-h asbypouring into a mold not shown entirely covering the main portion ofs'aid member with the faces 16 and ears 19 of the extensions 15 aloneexposed, such exposures being at the top `17 of the tie or'concreteblock 11 for the purposes heretofore noted. The vibrations incident tothe operation of the railroad will be taken up by the metal member 10thereby insuring longlife to the concrete portion 1i of the tie as wellas strengthening the concrete against vertical stresses as well as 20lateral and longitudinal stresses by the relative perpendicularrelations between the main portions of the member 10 and the ears 14,14.

While 't'he form of the invention herein set forth and described isbelieved to be the preferred embodiment thereof, it will be neverthelessunderstood thatminor changes may be made therein without departing fromthe spirit andscope of the invention as claimed.

l"Vhat I claim as new is:

1. A railway tiecomprising a sheet metal strip having transverseslits inits opposite edges forming intervening ears adapted for alternatebending in opposite directions .for the transverse seating of railsthereon,

a metal reinforcing member comprising an elongated sheet metal stripembedded in said body with oppositely projecting anchoring portions atits upper and lower edges, integral extensions, upon said strip withtheir upper edges flush with the top of said. body adapted for seatingthe rails, thereon, inwardly projecting ears at` the outer edges of saidextensions for engaging the outer flanges of rails, inwardly project ingcurved arms upon the inner edges of. the extensions within said body,bolts positioned upright in the body having eyes mounted upon said armsand clamps removably secured upon said bolts adapted for overlying theinner flanges of rails when positioned in track formation upon thedevice..

In testimony' whereof I aiiix my signature.

JOHN NELSON.
